ARIA defines the following roles as range widgets, which means they communicate a value that is typically numeric and constrained to defined limits.
For example, a spin button for choosing a day within the month of January would allow integer values that range from 1 to 31. In some cases, the value is represented numerically, but is not presented as a number to users. For instance, a spin button for choosing a day of the week could support values from 1 to 7 but they could be presented to the user as day names, e.g., "Monday", "Tuesday", etc.
This section describes considerations for using the following four properties that communicate characteristics of a range widget:
|Defines the minimum value allowed by a range widget.
|Defines the maximum value allowed by a range widget.
Defines the current value of a range widget.
This value is a number greater than or equal to
aria-valuemin and less than or equal to
aria-valuemax (if they are specified).
|If a numeric value is not sufficiently descriptive, this property can define a text description of the current value of a range widget.
